Bastion One

Vast multi-level lunar fortress with corridors, rec rooms featuring jellyfish aquariums.

Bastion One emerges in Light Bringer as a sprawling lunar fortress whose multi-level corridors and rec rooms—complete with jellyfish aquariums—serve as both a strategic stronghold and a haunting reminder of the Society’s once-unassailable power. Across the series, the fortress evolves from a distant symbol of Gold dominance into a contested battleground where the Rising’s forces finally breach the Moon Lords’ inner sanctum. Its transformation underscores the saga’s shift from rebellion on the surface worlds to the ultimate struggle for Luna itself.
